What is a betta fish sorority tank?

In this post, we will answer the question “What is a betta fish sorority tank?”. We will understand what a sorority tank is and what are some of the requirements for this type of tank.

What is a betta fish sorority tank?

A betta sorority is merely a catch-all term for a group of female betta fish who share a tank. 

Your female betta may live in a relatively tranquil sorority setting, but that isn’t always the case. She’ll have to make an extra effort to compete for food with everyone else, she’ll have to use her to establish her area, and she’ll have to cope with the stress of living in close quarters with other possessive and hostile fish.

Because stress is the most common cause of disease outbreaks in fish housed in enclosures, greater effort should be placed on reducing stress for all fish in the tank. This is why any aquarium owner has to pay special attention to the quality of the water in the aquarium. Remember that when the water quality in the tank is poor, your fish’s immunity is likely to be compromised. The fish will be more susceptible to infections if they have only a week’s immunity.

Minimum tank size for a betta fish sorority tank

Having a minimum tank volume of 10 gallons is essential to keep your Betta Sorority together is recommended. The tank might be larger than the minimum requirement of 10 gallons because female bettas require enough space to comfortably build their territories due to their territorial nature. When the space becomes too tiny for them, additional battles may break out, causing tension and possibly death. A good fish tank should be broader rather than higher, as this gives the fish more room to spread around and even get away from bullies.

Add as much protection as possible 

It’s best to provide as much cover as possible for your fish, which you may do using driftwood, rocks, vegetation, and freshwater plants, among other things. This type of cover provides much-needed protection from bullies and, as a result, helps to reduce fighting among the fish in the tank. 

You should keep a few things in consideration when it comes to placing your Betta fish 

Once you have it all set, including the aquarium and the water, the most difficult decision you will have to make will be which bettas will live in the aquarium. It is critical to select only the greatest bettas because even a single bad betta can cause havoc in the tank. In such a case, here are a few ideas on how to choose the greatest female bettas for your sorority tank.

It’s crucial to get the appropriate number

Have at least four and no fewer than four bettas in the same tank. Having even more of them in the tank is preferable. If you have fewer than four bettas in the same tank, you run the risk of the weakest betta being severely bullied, which could lead to death. However, even if you add a lot of bettas to the tank, make sure that the total number of bettas in the tank does not surpass 6 in a 10-gallon tank. In a tiny tank, having too many fish might be disastrous. 

Be sure it’s a female betta 

There is one piece of advice that many people, including some seasoned aquarists, are unaware of. Any female betta who does not have an ovipositor in her abdomen that has a white speck is most likely a male who has been confused for a female. There’s a good probability you’ll pick a betta fish with shorter fins for a female throughout the selecting process! 

Get female betta fish who are related 

If at all feasible, consider females who were near to each other whilst in their cups. Because they are familiar with each other, they have been observed to be less aggressive to each other.

Choose female bettas who are younger

It is better to choose female bettas that are still young when taking them with you because they are not as aggressive as older ones. 

Include bettas with a variety of appearances.

It’s advisable to choose bettas that seem slightly different from each other when putting them in a single tank. It’s much better if the bettas are all various types. This reduces the likelihood of aggression between them because they have been seen not to attack fish that are not closely related to them. 

Introduce all of them together

When it’s time to place the betta fish in the tank, it’s best to do it all at once so that they don’t get tangled up in one another. This will lessen the likelihood of their attempting to establish territories and competing for space. 

In sororities, there is a lot of aggression

Many new aquarists, particularly those who have yet to speak with sororities, are unfamiliar with the appropriate level of hostility in the tank. Despite the fact that animosity is a typical impulse in female betta fish for competing for food and establishing territory, it is not a good idea to ignore it when it occurs. It’s natural for your female betta sorority to fight each other when you initially introduce them to the tank. Body slapping, chasing, flaring, and biting are all examples of this behaviour.

Under normal circumstances, though, the fighting will begin to fade after a few days and eventually cease. There are instances, though, when you will undoubtedly need to intervene to help rescue things, particularly if you witness sustained fighting with evident harm. It’s possible that removing the aggressor and placing her in a separate tank is the best option. Another case in which you may be required to act is to protect a weaker female who is being harassed and transfer her in a separate container from the abusers, as described above. 

Prior to setting up a betta fish sorority aquarium, you should be aware of a few important considerations

You must first grasp the biology of female bettas before you can set up a sorority tank. We all know that putting multiple male bettas in the same aquarium can make them “bitchy.” Female bettas are more social than male bettas, although they aren’t fully docile. Female bettas are territorial as well and will engage in minor “fights” while figuring out the personality order. 

Depending on the size of the tank, the betta sorority should be composed of at least four to five females, but not more than 10. It is not difficult to set up a female betta sorority tank, but several measures must be followed to be successful.

How to set up your betta sorority aquarium 

It is arguable what the bare minimum tank size for a female betta sorority tank should be. Some aquarists claim that tanks with a capacity of at least twenty gallons are the most successful. The female bettas are more inclined to fight in a smaller tank. 

An aquarium size of 20 to 30 gallons is recommended by experienced betta keepers. A 20-gallon sorority, on the other hand, can be very effective – though you may need to remove a bully female if she refuses to settle down and become friendly.

Frequently Asked Questions (FAQs): What is a betta fish sorority tank?

For a betta sorority, what size tank do you need? 

It’s preferable to go with a minimum of 20 gallons because you should keep at least five females in your sorority (75 litres). Advice: When it comes to aquariums, bigger is always better. The more stable the water conditions are in a larger aquarium, the better. 

A sorority is made up of how many betta fish. 

In a sorority, there should always be at least five bettas. While three can be kept together, there’s a danger that two of them will bully the third. Try putting the bettas in the tank all at once. 

How can I feed my betta sorority? 

Because betta fish are carnivores, they require a high-protein diet. Betta pellets or flakes, as well as frozen brine shrimp, live brine shrimp, and blood worms, are available as treats. At first, the newcomer’s sorority will not want to eat much since they will be disturbed from adapting to a changing tank habitat; however, this will pass quickly.

Is it difficult to be a member of a betta sorority? 

Bettas are always in a state of agitation. Many people who have Betta sororities swear that their fish never fight or flare-up. Unfortunately, they are unaware that such submissiveness is a sort of extreme stress in and of itself. 

Is it true that betta fish can become lonely? 

Betta fish are possessive by instinct, and they must not be maintained with other betta fish because they will battle and injure each other, which will frequently result in death as a result of the fighting. They are unlikely to become lonely in their tank, although they may become bored if it is small. 

What are the benefits of betta sororities? 

Bettas can form a sorority to live together. Betta sororities continue to be a source of contention in the fish world today. While some owners are adamantly opposed to Betta sororities because of the possibility of stress among tankmates, others have successfully maintained them for years.
